screw 21 or the like to the outer side of the slide 1.4 at theupper'edge thereof and overlapping the iange or guide 12 above thechannel 13. Said stop 21 is movable between a pair ot' stops 23depending from the opposite ends of overlapping` slotted bars 23 securedon the upper edge of the flange or guide 12 by means of screws 23" whichextend through the slots of saidbars. l/Vhen the screws are loosened,the bars 23 can be adjusted longitudinally to position the stops 23according to the desired adjustment, for determining the length ofthefmortise or slot. The flange or guide 12 is preferably graduated, .asat A21, to assist in positioning the stops 23.

'A depth slide 24 is mounted for movement toward and away 'from theobject andthe base 7. Thus, said slide 24'has sleeves 27 slidable onrods 25 `carried by and extending horizontally from the base? below theguide 12 and slide 14.

A depth gage is provided for limiting the movement oft the slide 24 onthe rods 25 toward the base 7 and object, to thereby determine the depthof a mortise. This gage includes a rod 33 vsecured to and extending fromthe base 7 at one endthereot adjacent to andA parallel with one of therods 25, and stop arm 33 mounted on said rod 33 for sliding and turningmovements. he arm 33 has a handle 35 for swinging it, to move said armagainst the corresponding rod 25,

i as seen in dotted lines in Fig. 1, or to swing said arm away from saidrod 25, as seen in full lines yin said Fig. 1. An adjusting collar 34 isslidable on the rod 33 and is secured in place by means of a set screw34 carried by the collar, and saidcollar can be readily adjusted toposition the stop 33 and limit the movement thereof on the rod 33 towardthe base. When the arm 33 is swung away from the corresponding rod 25,the slide 24 can move up to the base 7, 4but when said arm 33 is swungagainst said rod 25, it will stop. the movement of the slide 24 at apredetermined position, to thereby limit the depth of the mortiseaccordingly.

The slide or member 24 has a guide or slideway 27 arranged verticallyand rising perpendicularly from the lower edge portionof said slidebetween theends of said slide, and a slidevvor block is slidableupwardly and downwardly in said guide or slot 27, and has a circularopening or bore 23 extending therethrough transversely ot the slide 24and guide 27. The slide 40 has a clamping plate y40 at one side held bya clamping bolt 40 to clamp said slide in its adjusted position.

The auger bit 43 or equivalent tool is rotated by a driving or operatingmechanism ley wheel 42 is secured on the spindle 37 between saidbushings for retaining the spindle in place, and a belt 44 passes aroundsaid pulley vwheel for rotating said spindle, and is guided betweenrollers 45. The shaft or shank. 33 which carries the bit. or tool 43v.is

.received by the tubular spindle 37, and said spindle has ascrew-threaded portion 37 at that end opposite to the bit into which thescrew-threaded terminal 38 of the shaft 33 isl secured, for fasteningsaid shaft to the spindle. rlhe shaft has a collar 33"thereon to bearagainst that end .of thespindle opposite to the screwthreaded end, :torfastening the shaft securely to the spindle, and the bit or tool 43projects beyond the collar 38.

rThe bushing 36' is veXteI'ided from'jthe yokeA 26 in order to `enterthe opening-23 of the 'slide or block 40so `as to provide a detachableslip connection between the driving mechanism and the portable ormovable device. The extended portion ,of the bushing 36 is convenientlyslipped in the opening 28,

Y for assembling the mechanism and device,

and in order to hold them assembled, said bushing has an annular groove39 -in the eX- tended portion thereof to receive a ballor catch 41vslidable in the slide or block 40 and 'projected' by a spring 41coninecl be hind said ball. When the slide 40 and bushing 36 are fittedtogether, the ball or catch r41 is pressed into the boire or socket',and

when the parts are moved together, said ball will snap into the groove39, thereby hold-I ing the yoke 26 and slide 40 together, but permittingsaid parts to turn relatively, when the device is moved longitudinally.

lThe bushingv36 can thus turn ink theysli'del 40. llVhenthedrivingmechanismand dey vice are thus assembled, the bit or tool can beattached by sliding the shaft 3S into Vthe spindle 37 and screwing saidshaft into place. The bit is thus secured to the rotary spindlefh37 o'tthe driving' mechanism, and.. vsuch spindle and bit will be adjustedwith the slide 40 upwardly and downwardly. rthe terminal portionAor,lnishing 36 of the driving mechanism is thus convenientlyassembledwith the device for adjustment therewith, to positionthe bit or toolaccordingly, andina like manner other devices yor attachments can beused interchangeably with the mortising device, by

having such devices eachv equipped with a slide or block to fit on thebushing 36. Various devices or attachments for doing different kinds ofwork can thus be used interchangeably with the driving mechanism.

A gage is provided for readily determining the transverse positions ofthe mortises or slots in the stiles or other objects. Thus, the slide ormember 24 has a slot 50 extending parallel with the guide 2T at one sideof the slot thereof, and bolts or stems 51 are disposed in the slot forlongitudinal adjustment in said slotto different positions, and havestops or heads 52 for the contact of the block or slide 40 to limit theupward and downward movement thereof. Nuts 53 are threaded on theboltsor stems 51 for clamping the stops 52 in their desired adjustments,and graduations 54 can be provided along the slot 50 for convenientlypositioning the stops 52. Thus, when the bolt 40 of the slide 40 isloosened,.said slide can be readily moved from one 'position against onestop 52 to the other position against the other stop 52, and said stops;thereby enable the position of the slide or block 40 4to be changedquickly, for cutting parallel mortises or slots. By adjusting the stops52, the transverse positions of the mortises or slots with respect tothe object can be adjusted, to space the mortises or slots the desireddistances from the edges of the object and from one another.

The slide or work holder 14 has an opening extending from one side tothe other, to accommodate the auger bit 43 in the different positions ofsaid bit and slide, and said slide has vertical openings or slotsA 61 inthe ends thereof for the reception of the window frame stile 62, boardor other object which is inserted on edge into the slide, as seen inFig. 3.

A work clamp is: carried by the slide or holder 14 and includes a stubshaft 63 mounted for turning movement in one end portion of the slide 14and having' a cam 64 working within a slot in said slide to bear againstthe stile or board 62, and clamp same against the back of the slide orholder 14. A hand lever 62 is secured to the shaft 63, and when raisedwill turn the cam 64 to bind the object in place.

In using the device, the slide or block 40 is assembled with the drivingmechanism, by fitting the bushing 36 in said slide, and the ball 41 willsnap into the groove 39, to hold the mechanism and device assembled. Thebit or tool 43 is then attached b y inserting the shaft or stem 38thereof into the tubular spindle 37 and screwing said shaft into placewith the spindle. The stile or board 62 is then inserted into the slideor holder 14, the bit 43 being retracted, and said stile Orboard isclamped in said slide or holder swinging the hand lever or arm 66. Thestile or board is thereby securely held in potermine the upper and lowerpositions of the auger bit 43. Thenby clamping the slide or block 40 inone position against the corresponding stop 52, and after swinging thestop arml 33 to position againstthe corresponding rod 25, the slide 24is moved toward the work, thereby presenting the bit 43 to the face ofthe stile or board 62, and by swinging the lever 17, the slide 14 andstile 62 are slid longitudinally, for cutting or routing a mortise inthe stile at the de sired transverse posit-ion and of the predetermineddepth and length. The depth of the mortise is determined by the positionof the stop arm 33, and the length of the mortise by the stops 23. Byswinging the stop arm 33 out of the way of the slide 24, the bit'43` cannow be moved further int-o the stile 62, to pass entirely through the'stile, and the slide 14 is then moved so that the bit cuts a' slot 67 inthe stile, but the slide 14 is not moved sufficiently to bring the stop21 aga-inst the stops 23, thereby making the slot 67 of shorter lengththan the shallow mortise 68.l Theinortis'e thus formed provides a slot`l67 through the stile or board, with shallow portions beyond the ends oflsuch slot, for receiving the housing of a sash cord pulley used onwindow frames, as well known.

By loosening the block or slide 40 and bringing same against the otherstop 52, a parallel'mortise of the same kind can then be cut inthe stileor board.,

Various sizes and positions of mortises can thus be produced, which isespecially useful for making the pulley mortises of window frames, andbits 43 of different diameters can be used interchangeably, for making"mortises of different widths. The lengths and depths, and also thetransverse positions of the mortises can be readily determined by thegages and adjustments provided. Furthermore, by loosening the screws 11and turning the plate or member 10, the slide 14 and object can bepositioned either at right angles or at an acute or obtuse angle withthe bit 43, to make the end walls of the mortises either at right orother anglesv with the sides of the objects.

The work can be done quickly and easily, without the labor and timerequired as when doing the work with an ordinary bra-ce and bit.Furthermore, the work is done accurately and neatly, and without apossibility of Al'Ji spoiling the job, because the adjustments `madewill define and limit the movement of the bit or cutter. f i
